Abstract

MODA, Evelise Moncaio; HORII, Jorge  and  SPOTO, Marta Helena Fillet. Edible mushroom Pleurotus sajor-caju production on washed and supplemented sugarcane bagasse. Sci. agric. (Piracicaba, Braz.) [online]. 2005, vol.62, n.2, pp. 127-132. ISSN 0103-9016.  http://dx.doi.org/10.1590/S0103-90162005000200006.

Traditionally, the cultivation of Pleurotus sajor-caju is performed on different composted and pasteurized agricultural residues. The objective of this study was to investigate whether traditional composting and pasteurization processes could be replaced by washed and supplemented (mineral or organic) sugarcane bagasse. In one experiment, fresh sugarcane bagasse was immersed in hot water at 80°C for two hours (control) or washed in fresh water for one hour using an adapted machine for residue treatment. In another experiment, fresh sugarcane bagasse was washed in fresh water (control), and supplemented with corn grits (organic supplementation), or supplemented with nutrient solution (mineral supplementation). In the first experiment, the washed bagasse presented a average biological efficiency (ABE) of 19.16% with 44% contamination, and the pasteurized bagasse presented a ABE of 13.86% with 70% contamination. In the second experiment, corn grits presented the poorest performance, with a ABE of 15.66% and 60% contamination, while supplementation with the nutrient solution presented a ABE of 30.03%, whereas the control of 26.62%. Washing fresh sugarcane bagasse could suppress the pasteurized substrate in Pleurotus sajor-caju production, compensating a reduced ABE with a faster process.
